+=head1 NAME
+
+Encode - character encodings
+
+=head1 SYNOPSIS
+
+ use Encode;
+
+=head1 DESCRIPTION
+
+The C<Encode> module provides the interfaces between perl's strings
+and the rest of the system. Perl strings are sequences of B<characters>.
+
+The repertoire of characters that Perl can represent is at least that
+defined by the Unicode Consortium. On most platforms the ordinal values
+of the characters (as returned by C<ord(ch)>) is the "Unicode codepoint" for
+the character (the exceptions are those platforms where the legacy
+encoding is some variant of EBCDIC rather than a super-set of ASCII
+- see L<perlebcdic>).
+
+Traditionaly computer data has been moved around in 8-bit chunks
+often called "bytes". These chunks are also known as "octets" in
+networking standards. Perl is widely used to manipulate data of
+many types - not only strings of characters representing human or
+computer languages but also "binary" data being the machines representation
+of numbers, pixels in an image - or just about anything.
+
+When perl is processing "binary data" the programmer wants perl to process
+"sequences of bytes". This is not a problem for perl - as a byte has 256
+possible values it easily fits in perl's much larger "logical character".

+
+=head1 ENCODINGS
+
+=head2 Characteristics of an Encoding
+
+An encoding has a "repertoire" of characters that it can represent,
+and for each representable character there is at least one sequence of
+octets that represents it.
+
+=head2 Types of Encodings
+
+Encodings can be divided into the following types:
+
+=over 4
+
+=item * Fixed length 8-bit (or less) encodings.
+
+Each character is a single octet so may have a repertoire of up to
+256 characters. ASCII and iso-8859-* are typical examples.
+
+=item * Fixed length 16-bit encodings
+
+Each character is two octets so may have a repertoire of up to
+65,536 characters. Unicode's UCS-2 is an example. Also used for
+encodings for East Asian languages.
+
+=item * Fixed length 32-bit encodings.
+
+Not really very "encoded" encodings. The Unicode code points
+are just represented as 4-octet integers. None the less because
+different architectures use different representations of integers
+(so called "endian") there at least two disctinct encodings.
+
+=item * Multi-byte encodings
+
+The number of octets needed to represent a character varies.
+UTF-8 is a particularly complex but regular case of a multi-byte
+encoding. Several East Asian countries use a multi-byte encoding
+where 1-octet is used to cover western roman characters and Asian
+characters get 2-octets.
+(UTF-16 is strictly a multi-byte encoding taking either 2 or 4 octets
+to represent a Unicode code point.)
+
+=item * "Escape" encodings.
+
+These encodings embed "escape sequences" into the octet sequence
+which describe how the following octets are to be interpreted.
+The iso-2022-* family is typical. Following the escape sequence
+octets are encoded by an "embedded" encoding (which will be one
+of the above types) until another escape sequence switches to
+a different "embedded" encoding.
+
+These schemes are very flexible and can handle mixed languages but are
+very complex to process (and have state).
+No escape encodings are implemented for perl yet.
+
+=back
+
+=head2 Specifying Encodings
+
+Encodings can be specified to the API described below in two ways:
+
+=over 4
+
+=item 1. By name
+
+Encoding names are strings with characters taken from a restricted repertoire.
+See L</"Encoding Names">.
+
+=item 2. As an object
+
+Encoding objects are returned by C<find_encoding($name)>.
+
+=back
+
+=head2 Encoding Names
+
+Encoding names are case insensitive. White space in names is ignored.
+In addition an encoding may have aliases. Each encoding has one "canonical" name.
+The "canonical" name is chosen from the names of the encoding by picking
+the first in the following sequence:
+
+=over 4
+
+=item * The MIME name as defined in IETF RFC-XXXX.
+
+=item * The name in the IANA registry.
+
+=item * The name used by the the organization that defined it.
+
+=back
+
+Because of all the alias issues, and because in the general case
+encodings have state C<Encode> uses the encoding object internally
+once an operation is in progress.
+
+I<Aliasing is not yet implemented.>
+
+=head1 PERL ENCODING API
+
+=head2 Generic Encoding Interface
+
+=over 4
+
+=item *
+
+ $bytes = encode(ENCODING, $string[, CHECK])
+
+Encodes string from perl's internal form into I<ENCODING> and returns a
+sequence of octets.
+See L</"Handling Malformed Data">.
+
+=item *
+
+ $string = decode(ENCODING, $bytes[, CHECK])
+
+Decode sequence of octets assumed to be in I<ENCODING> into perls internal
+form and returns the resuting string.
+See L</"Handling Malformed Data">.
+
+=back
+
+=head2 Handling Malformed Data
+
+If CHECK is not set, C<undef> is returned. If the data is supposed to
+be UTF-8, an optional lexical warning (category utf8) is given.
+If CHECK is true but not a code reference, dies.
+
+It would desirable to have a way to indicate that transform should use the
+encodings "replacement character" - no such mechanism is defined yet.
+
+It is also planned to allow I<CHECK> to be a code reference.
+
+This is not yet implemented as there are design issues with what its arguments
+should be and how it returns its results.
+
+=over 4
+
+=item Scheme 1
+
+Passed remaining fragment of string being processed.
+Modifies it in place to remove bytes/characters it can understand
+and returns a string used to represent them.
+e.g.
+
+ sub fixup {
+ my $ch = substr($_[0],0,1,'');
+ return sprintf("\x{%02X}",ord($ch);
+ }
+
+This scheme is close to how underlying C code for Encode works, but gives
+the fixup routine very little context.
+
+=item Scheme 2
+
+Passed original string, and an index into it of the problem area,
+and output string so far.
+Appends what it will to output string and returns new index into
+original string.
+e.g.
+
+ sub fixup {
+ # my ($s,$i,$d) = @_;
+ my $ch = substr($_[0],$_[1],1);
+ $_[2] .= sprintf("\x{%02X}",ord($ch);
+ return $_[1]+1;
+ }
+
+This scheme gives maximal control to the fixup routine but is more complicated
+to code, and may need internals of Encode to be tweaked to keep original
+string intact.
+
+=item Other Schemes
+
+Hybrids of above.
+
+Multiple return values rather than in-place modifications.
+
+Index into the string could be pos($str) allowing s/\G...//.
+
+=back
+
+=head2 UTF-8 / utf8
+
+The Unicode consortium defines the UTF-8 standard as a way of encoding
+the entire Unicode repertiore as sequences of octets. This encoding
+is expected to become very widespread. Perl can use this form internaly
+to represent strings, so conversions to and from this form are particularly
+efficient (as octets in memory do not have to change, just the meta-data
+that tells perl how to treat them).
+
+=over 4
+
+=item *
+
+ $bytes = encode_utf8($string);
+
+The characters that comprise string are encoded in perl's superset of UTF-8
+and the resulting octets returned as a sequence of bytes. All possible
+characters have a UTF-8 representation so this function cannot fail.
+
+=item *
+
+ $string = decode_utf8($bytes [,CHECK]);
+
+The sequence of octets represented by $bytes is decoded from UTF-8 into
+a sequence of logical characters. Not all sequences of octets form valid
+UTF-8 encodings, so it is possible for this call to fail.
+See L</"Handling Malformed Data">.
+
+=back
+
+=head2 Other Encodings of Unicode
+
+UTF-16 is similar to UCS-2, 16 bit or 2-byte chunks.
+UCS-2 can only represent 0..0xFFFF, while UTF-16 has a "surogate pair"
+scheme which allows it to cover the whole Unicode range.
+
+Encode implements big-endian UCS-2 as the encoding "iso10646-1" as that
+happens to be the name used by that representation when used with X11 fonts.
+
+UTF-32 or UCS-4 is 32-bit or 4-byte chunks. Perl's logical characters
+can be considered as being in this form without encoding. An encoding
+to transfer strings in this form (e.g. to write them to a file) would need to
+
+ pack('L',map(chr($_),split(//,$string))); # native
+ or
+ pack('V',map(chr($_),split(//,$string))); # little-endian
+ or
+ pack('N',map(chr($_),split(//,$string))); # big-endian
+
+depending on the endian required.
+
+No UTF-32 encodings are not yet implemented.
+
+Both UCS-2 and UCS-4 style encodings can have "byte order marks" by representing
+the code point 0xFFFE as the very first thing in a file.
+
+=head1 Encoding and IO
+
+It is very common to want to do encoding transformations when
+reading or writing files, network connections, pipes etc.
+If perl is configured to use the new 'perlio' IO system then
+C<Encode> provides a "layer" (See L<perliol>) which can transform
+data as it is read or written.
+
+ open(my $ilyad,'>:encoding(iso8859-7)','ilyad.greek');
+ print $ilyad @epic;
+
+In addition the new IO system can also be configured to read/write
+UTF-8 encoded characters (as noted above this is efficient):
+
+ open(my $fh,'>:utf8','anything');
+ print $fh "Any \x{0021} string \N{SMILEY FACE}\n";
+
+Either of the above forms of "layer" specifications can be made the default
+for a lexical scope with the C<use open ...> pragma. See L<open>.
+
+Once a handle is open is layers can be altered using C<binmode>.
+
+Without any such configuration, or if perl itself is built using
+system's own IO, then write operations assume that file handle accepts
+only I<bytes> and will C<die> if a character larger than 255 is
+written to the handle. When reading, each octet from the handle
+becomes a byte-in-a-character. Note that this default is the same
+behaviour as bytes-only languages (including perl before v5.6) would have,
+and is sufficient to handle native 8-bit encodings e.g. iso-8859-1,
+EBCDIC etc. and any legacy mechanisms for handling other encodings
+and binary data.
+
+In other cases it is the programs responsibility
+to transform characters into bytes using the API above before
+doing writes, and to transform the bytes read from a handle into characters
+before doing "character operations" (e.g. C<lc>, C</\W+/>, ...).
